Wheel Speed Sensor Fault

[mikeyerfdog]

Hi All,

My wifes C4GP Mk2 has the normal chrismass tree of fault. (ABS, ESP etc etc) I hooked it upto Diagbox and it showed rear right speed sensor. Great i thought, changed the sensor and the fault came back.

Thinking about it, it comes up more when it is wet. I guess i am going to have to trace the wiring. Does anyone know where the speed sensor connects into to? Where is the other end of the cable so i can check from point to point? Anyone have the pin numbers and control location.

Due to go to cornwall next week so will be putting 1,000+ miles on the car.

Any help would be great.

Thanks

My advice is to check the actual pins and connectors in the wiring block for the same sensor you replaced - we had a member recently with the same issue and it was a lose pin in the connector IIRC.

Thanks, I checked that one. I want to check all the wiring right back to the controller. Where is that contrller so i can check that end's multiplug?

It will go back with the others to the ESP / ABS ECU which is at the rear of the engine bay near the left front wing (standing in front of the bonnet).

I think you might me right tho. I have the 2pin plug a wiggle and it cleard last night. Will get the wheel off this weekend and confirm for sure.

Thanks for your input tho...

No worries - best of luck with it. Once you check the Pin, give it a clean with some Servisol or other electrical contact cleaner too.
